You probably won't like this but here goes: I was once told by an old craftsman if you are going to make something and say you hand crafted it -then make it yourself .
When you turn a piece and add anothers product -you ar not crafting yourself.
Learn to turn the piece -then be proud of saying I crafted this .If not order the tone boards already turned ,run down to lowes and get piece of plastic conduct cut and assemble --same thing . Sorry to blow bubbles but craft is learning and doing .
I won't disagree too much with you, BUT, I have not and will not claim to have "crafted" a duck call when I build one this way. Using this argument, only a select few on this forum are true craftsmen because we take something someone else made (component sets) and create a pen instead of making it 100% in shop.
I know my limits at this time and am choosing to use a proven assembly to make my calls sound as good as I can. My job is to make it look good, someone else's job to make it sound good. If you have looked at some of the great calls made by the guys at Duck Commander you will know that a lot of them are about function, not style. I have been asked to make one for both.
When I sell these calls I will be able to say that I crafted the body and (insert company name) made the reed assembly. Like I said, don't completely disagree with you but I won't be claiming anything that I haven't created.
